The Impact of Immigration on the United States Economy closely examines the effects of immigration on the United States economy from 1940-1980. Using multiple linear regression, Kposowa found that overall, immigration has had positive effects on the US economy, especially in terms of increasing native earnings and native socioeconomic attainment. However, he also found that immigration has negative effects on minority earnings, particularly those of African Americans. Contrary to popular belief, Kposowa reveals how immigrants as a population are significantly less likely than native born people to be on public assistance or social security. This fascinating study debunks many myths surrounding immigration and concludes by offering practical public policy recommendations.
